These tables cover ABEC and ISO tolerances for ball bearings.

The section of our bearing part number that specifies the grade is found near the end, preceded by the
country of manufacture code. The following list shows most of our country/precision designations.

No country of manufacture is specified in the part number of Abec 1 bearings since they are the most common bearings
and supplies may be obtained from a number of different countries as required by demand and/or pricing. The majority of our
Abec 1 bearings are Japanese manufactured. A manufacture code is printed on the label which can be used to determine the
country of manufacture of a particular batch.

Each table covers either inner or outer ring tolerances for a defined size range as specified in the headers. Scroll down to see all tables...
